QUANTITY OF BEER.

Patented July 20, 1809.

- Application filed October 2, 1908. Serial No. 455,904.

To all whom it may concern:

tus wherein the liquid is first drawn into a measuring cylinder from asource of supply and then drawn from the measuring cylinder through adispensing faucet so that but a definite quantity ofliquid can be drawnbyone operation of the faucet.

My invention is primarily designed for dispensing beer and to regulatewhat is known as the pint trade. 1

The main object of my invention is to avoid any waste of liquid whenchanging from one source of supply to another and to insure that thefirst liquid drawn from the new source will be of the full measuredquantity.

To these ends my invention consists in providing an apparatus fordrawing a measured quantity of liquid with means for changing from onesource ofsup'ply to another, when the first has become exhausted, to-

gether with means for venting or freeing the.

air from the pipes and intermediate connections ,of the empty end of thesystem previous to connecting the new supply, so that the new supplycan. immediately. fill the empty end and a full measured quantity drawnat the first draft from the new supply. My invention also consists inthe details of construction and combinations of arts hereinafter moreparticularly describe andthen specified in the claims. I

In ,apparatus designed for drawing a measure quantity of liquid from asource of supply, the measuring cylinder has been connected to thesource to obtain its supply and 1 then the liquid drawn from themeasuring cylinder; This is true of my apparatus, but

in apparatus heretofore in use when the source of s ipply has becomeexhausted the 'pipes connecting the measuring cylinder with the sourceand the empty side of the cylinder become full of air, more oralesscharged, due to drawing the last measured quantity from the other sideof the piston in the cylinder so that if a liquid such as beer is tityof liquid drawn from the measuring cylinder will not be equal to thefull amount,

away. r

, In my improved apparatus, instead of the incoming onnew supply of beerdriv ng the air out of the connecting pipes and the openor empty end ofthe cylinder, the pi s and will be mixed with air and has to be throwncylinder are freed of air first and by t e same operation whichtransfersto the newsupjply and then the new beer is free to completelyand immediately fill both the connecting pipes and the open end of themeasuring cylinder without being mixed with air.

In the accompanying drawings, Figure 1 illustrates a general view of myimproved apparatus. Fig. 2 is a longitudinal vertical central sectionthrough the dispensing faucet. Fig. 3 is a central section throughtheswitch for changing from one source of supply to another. Fig. 4 is atransverse section taken on the line E, E Fig. 2.

hereinafter called the dispensing faucet, and

which controls the admission of liquid to they ly and also controls 'thedrawing of measuring cylinder 3 from the sourceof sulpt e 'quidtherefrom.

indicates the b ody; of a three-way valve, hereinafter called a switch,connected to both sources of sup ly and by means of which the change isma e from-one'source to the other 5 when either one becomes exhausted.

The body 5 of the switch is provided with a seat 6 and ports or passages7, Sand 9 extending therethrough. The port or passage 7 communicates bya pipe 10 with one source 10 of supply while the passage 9 communicatesby a pipe 1 1 with the other source. The central port or passage 8establishes connection with the dispensing faucet through a pipe 12- aswill be hereinafter described. A disk valve 13 adapted to turn on theseat 6 is provided with ports 14 and 15 connected by a channel'16, theport 15 being permanently registered with the port or passage 8 whilethe port 14 registers with port 7 or 9 according to which source it isdesired to draw from, the movement of the valve being positively stoppedin either direction when the f ports areregistered by means of pins 19,20 projecting. laterally from the disk 13 engaging a sto 21 projectinginwardly from the body 5. he valve 13 is also provided with a spindle 17and a suitable operating handle 18 secured thereto. N Referring moreparticularly to Figs. 2 and 8, the body portion '4 of the dis ensingfaucet is provided with a seat'22 anc ports or passages 23, 24, 25extending longitudinallythroughthe same and with a port 26coinmuniicating with the discharge nozzle or outlet 27. A disk valve 28adapted to turn on the seat 22 is provided with a spindle 29 andsuitable operating handle 30. The valve 28 v is provided with ports 31,32, 33 and 34in the face thereof andadapted to register with the portsin the seat of the valve body. The

ports 31 and 34 in the valve are connected to eachother by a channel 35and the ports 32 and 33 are connected by a channel 36 so that the ports31 and 34 and the channel-35 will, in one position of the valve,establish com munication with the ports 23 and 25 and in the reversemovement with the ports 23 and 24. When the oorts 31 and 34 establishcommunication between orts 23 and 25,

- communication is establis 'ed betweenthe ports 24 and 26 by means ofports 32 and 33 and channel 36 and similarly when ports 23 and 24 are incommunication, ports 25 and 26 are in communication, the movement of 5the valve being limited in either direction by pins 37 and 38 hittingthe'stop 39 projecting throughthebody 4. The passage 23 in the valvebody is connected by the pipe 12 with the switch 5 and the passages 24.and 25 are connected by. pipes 40 and 41 to either end 'ofthe measurlngcylinder so that the li uid which passes through the switch '5 is'de'vered to the passage 23 from which it is alternately delivered to thepipes 40, 41 leading to either end of the measuring cylinder. It

passing from the pipes through a said trap or; cup

will also be noted that when the valve establishes communication betweenthe port 23 and the pipe 41 leading to one side of the cylinder,communication is established be-' tween the pipe 40 leading from theother side of the cylinder and the outlet 27 and vice versa.

Referring more particularly to Fig. 8 the measuring cylinder consists ofa cylindrical sleeve '3 provided with heads 42 and 43. The pipes 40 and41 are connected to the heads 42 and 43 respectively, the liquid ort 45in the head to t e inside of the cy linder, each head being providedwith a valve seat 44 on its inner side. At or near each end of thecylinder atrap or cup is located, being in communication with theinterior of the cylinder and consisting preferably of a sleeve 46 tappedinto the cylinder 3 and provided at the bottom with a cap 47 having ascrew-threaded connection with the sleeve 46 and adapted to close thelower openingtherein, a suitable compressible washer being locatedbetween the cap and the end of the sleeve to insure against leakage. Apiston 48 adapted to re- ,ciprocate within the cylinder 3 is providedwlth a boss 49 projectin laterally from either face. A compressib ewasller 50 in serted in the end of each boss engages the seat 44 of the'ort 45 and acts as a valve to close communication withthe pipe 40 or 41according to which end of the cylinder the piston travels-to. The pistonis stopped in its travel in either direction just as it reaches the cup46 by means of the boss 49 and valve seat 44 so that any dirt or foreignsubstance which entered the cylinder with the beer will drop to thebottom or side of the cylinder and be forced along and into the cup 46from which it can readily be removed by unscrewing the cap 47. Thepiston proper consists merely of two metallic disks 48 spaced somewhatapart to insure its straight travel and' connected together'by a hub 51,as I find that by. the use of a rigid metallic piston without the emloyment of piston rings or packing of any 'nd between its periphery andthe sides of' the cylinder. it works easier and does not stick orcorrode as is the case Where rings or packing are used when measuringbeer. A vent hole or ort 55 lo cated in the seat 6 of the switc 5 passesthrough the body of the switch and is. open to theatmosphere. A v

When ch from one source of suppl to the other, theport 14 in travelingfrom the port 7 to the port 9 registers with the port 55 which allowsthe air in the pipe 12 to escape to the atmosphere. For aninstance ofthe working of this part of my invention and referring to Fig. 8, I willassume that the keg connected to. the pipe 10 is empty, the last of theliquid therein having been used filling ther liquid'to draw from the kegconnected to the pipe 10, the pipe 12and cylinder 3 will merely becomefilled with air as the piston moves over due to drawing the liquid fromthe cylinder. The valve in the switch is then turned to establishcommunication between the pipe 11, connected to the new source, and thepipe 12, by means of the port 14, but be fore the port 14 reaches theport Qit registers with the vent port 55 whereby the air in the pipe 12and cylinder 3 passes out to the atmosphere and allows the beer from thenew suppl to immediately fill the pipe 12 and cylin er 3 as soon as theport 14 reaches the port 9. If "the pipe 12 and open end of the cylinderwere not freed fromair the new supply could not entirely fill thecylinder and as a consequence whatever liquid there would be in thisside of the cylinder would have to be, drawn off through the dispensingfaucet and wasted as it would not be a full measured quantity and wouldbe mostly foam.
